这是我的模型:

public class Items
    {
        public string Foo { get; set; }
        public string Bar { get; set; }
    }

控制器:

public ActionResult Index()
    {
        var model = new List<Items>
                        {
                            new Items
                                {
                                    Foo = "foo",
                                    Bar = "bar"
                                },
                            new Items
                                {
                                    Foo = "ai",
                                    Bar = "ia"
                                },
                            new Items
                                {
                                    Foo = "one",
                                    Bar = "two"
                                }
                        };
        return View(model);
    }

查看(索引):

@using (Html.BeginForm())
{
    for (int i = 0; i < Model.Count; i++)
    {
        <div onclick="$(this).remove();">
            @Html.TextBoxFor(model => model[i].Foo) <br/>
            @Html.TextBoxFor(model => model[i].Bar)
        </div>
    }
    <div>
        <input type="submit"/>
    </div>
}

我删除了第二对:

    <div onclick="$(this).remove();">
        <input name="[0].Foo" type="text" value="foo"> <br>
        <input name="[0].Bar" type="text" value="bar">
    </div>

    <div onclick="$(this).remove();">
        <input name="[2].Foo" type="text" value="one"> <br>
        <input name="[2].Bar" type="text" value="two">
    </div>

发布时,我只获得第一对("foo"和"bar").这是因为第三对有索引"2".我想得到两个对(不使用FormCollection.我希望它自动绑定).实际上,我在表单上有很多其他输入,所以我不想重新加载并重新附加每个输入的索引.你能帮助我吗?

我找到了解决方案,感谢 Amit Prajapati:

@using (Html.BeginForm())
{
    for (int i = 0; i < Model.Count; i++)
    {
        var identifier = Guid.NewGuid();
        <div onclick="$(this).remove();">
            @Html.Hidden("Index", identifier)
            @Html.TextBox("[" + identifier + "].Foo")
            <br/>
            @Html.TextBox("[" + identifier + "].Bar")
        </div>
    }
    <div>
        <input type="submit" />
    </div>
}
